We stayed at Mitch & Mam's for just over a week. The apartment is small and quiet - perfect as a base for exploring the sights of Bangkok. You should be aware that the apartment is at least 5 minutes walk from the nearest subway station and then some 20 minutes on the subway to get to the action of Bangkok.
The complex has very good security and walking around the streets at night felt safe. There's a great supermarket across the road and the free WiFi internet makes the use of Skype a breeze.
Apartment offers very good value for money.
